When do I use "No" and when do I use "Not"?

"No" + noun (no problem, no time). "Not" + adjective/adverb/verb (not ready, not now, did not go).

How do I remember the difference between "No" and "Not"?

Category test: is the next element a noun? Use "no" (no money, no time). Is it an adjective, adverb, or verb? Use "not" (not ready, not now, did not finish).

Did you know?

NO and NOT both contain the old negative particle "ne", but over time they specialized. "No" negates nouns ("no time", "no problem"), while "not" negates verbs, adjectives and adverbs ("not ready", "did not go"). That is why "She is no ready" is wrong, while "She is not ready" and "She has no time" are right.
